This problem is slightly different because there are two “s” letters. How many different ways can the letters in the word “physics” be arranged? This works because each letter in the word is unique and we are simply finding the maximum amount of ways 8 items can be ordered. How many different ways can the letters in the word “document” be arranged?įor this problem we simply take the number of letters in the word and find the factorial of that number. There is exactly 1 way to arrange 0 objects. 5 factorial is 5! = 5 x 4 x 3 x 2 x 1 = 120.There are 2 different ways to arrange the numbers 1 through 2. "The factorial n! gives the number of ways in which n objects can be permuted." For example: In mathematics, there are n! ways to arrange n objects in sequence. Factorial There are n! ways of arranging n distinct objects into an ordered sequence. The function is used, among other things, to find the number of way “n” objects can be arranged. What is a Factorial?Ī factorial is a function that multiplies a number by every number below it. You may want to copy the long integer answer result and paste it into another document to view it. You will get the long integer answer and also the scientific notation for large factorials. Instead of calculating a factorial one digit at a time, use this calculator to calculate the factorial n! of a number n.
